Add Comptroller Scott Stringer to the growing list of pols who say Mayor Bill de Blasio should do the job he was elected to do — rather than gallivanting around the country to satisfy his pipe dream of becoming president.

During an unrelated press conference in Lower Manhattan, Stringer said de Blasio should take a lesson from former Mayor John Lindsay, whose brief bid for the Democratic presidential nomination in 1972 failed miserably.

“I think [it’s a] challenge for any mayor of this city” to run for president while in office “as John Lindsay proved many years ago,” Stringer said. “This is a job that requires 24/7 day focus.”

“I always said we want him to go out and make speeches and be part of the national dialogue, but right now given the challenges that we are facing here, given the issues we are facing with economic development, it is best that he stays here and works closely with me because I love working side by side with him,” added Stringer, who is mulling running for mayor in 2021. “So I hope he stays around and works here.”
